Recent studies report high concentrations of haloacetic acids (HAAs), a prevalent class of toxic disinfection by-products, in swimming pool water (SPW). We investigated the removal of 9 HAAs by four commercial reverse osmosis (RO) and nanofiltration (NF) membranes. Under typical SPW conditions (pH 7.5 and 50 mM ionic strength), HAA rejections were >60% for NF270 with molecular weight cut-off (MWCO) equal to 266 Da and equal or higher than 90% for XLE, NF90 and SB50 with MWCOs of 96, 118 and 152 Da, respectively, as a result of the combined effects of size exclusion and charge repulsion...

Situations in which one partner is interested in having sex but the other partner is not "in the mood" are common in relationships. We extend previous work on sexual communal strength-the motivation to be responsive to a partner's sexual needs-to demonstrate that in addition to the motivation to meet a partner's need to have sex, the motivation to be understanding about a partner's need not to engage in sex is uniquely associated with sexual and relationship satisfaction. In Study 1, we adapted a measure of sexual communal strength for having sex (SCSS) to create a new measure of sexual communal strength for not having sex (SCSN)...

BACKGROUND: ABO incompatible kidney transplantation (ABOi-KT) is an important approach for overcoming donor shortages. We evaluated the effect of ABOi-KT on living donor KT. METHODS: Two nationwide transplantation databases were used. We evaluated the impact of ABOi-KT on overall living donor transplant activity and spousal donation as subgroup analysis. In addition, we compared the clinical outcome between ABOi-KT and ABO compatible KT (ABOc-KT) from spousal donor, and performed a Cox proportional hazards regression analysis to define the risk factors affecting the allograft outcomes...

Liver fibrosis is the consequence of hepatocyte injury that leads to the activation of hepatic stellate cells (HSC). The treatment of choice is Liver transplantation; however, it has many problems such as surgery-related complications, immunological rejection and high costs associated with the procedure. Stem cell-based therapy would be a potential alternative, so the aim of this study is to investigate the therapeutic potential of human umbilical cord mononuclear cells (MNC) and mouse bone marrow cells (BMC) against carbon tetrachloride (CCl4) induced liver fibrosis in mice and compare it with that of silymarin...

OBJECTIVES: Many authors argue that inconsistencies between studies of skeletal markers are based on different data collection protocols, especially when comparing age-related markers such as osteoarthritis. Less attention is given to the choice of statistical techniques that are used to test the hypotheses associated with the data. This paper addresses how different statistical techniques compare the prevalence of age-related skeletal indicators, specifically osteoarthritis. MATERIALS AND METHODS: Osteoarthritis prevalence was scored in eight postcranial joints in 243 adult individuals from seven prehistoric archaeological sites in Central California, and data was compared between three time periods [Early (4800-2800 BP), Middle (2800-1200 BP), and Late (1200-250 BP)] using commonly used statistical tests: chi-square, Fisher's exact, and odds ratios...

In transplantation, there is a critical need for noninvasive biomarker platforms for monitoring immunologic rejection. We hypothesized that transplanted tissues release donor-specific exosomes into recipient circulation and that the quantitation and profiling of donor intra-exosomal cargoes may constitute a biomarker platform for monitoring rejection. Here, we have tested this hypothesis in a human-into-mouse xenogeneic islet transplant model and validated the concept in clinical settings of islet and renal transplantation...

OBJECTIVE: To assess medical practices surrounding the use of topical ocular cyclosporine A across European Union nations. METHODS: Key stakeholders (ophthalmologists, hospital pharmacists, regulatory health authorities) from European Union member states were interviewed by telephone using a semi-structured, open-ended questionnaire. Ophthalmologists responded to questions about practice patterns of cyclosporine A use (prescription frequency, indication, dosage), pharmacists about cyclosporine A formulations (composition, manufacturing process, quality control, distribution), and the regulatory authorities about market authorization and pharmacovigilance for various cyclosporine A products...

Antibody-mediated rejection is associated with heterogeneous kidney allograft outcomes. Accurate evaluation of risk for graft loss at time of diagnosis is necessary to offer personalized treatment. In contrast with serological and molecular assessment, morpho-histological evaluation of antibody-mediated rejection lesions has not significantly evolved. This relies on Banff classifications designed to be of diagnostic discriminatory power rather than prognostic and face quantitative and qualitative limitations...

Cardiac allograft rejection (CAR) may occur after transplantation and remains silent, until hemodynamic deterioration takes place. Endomyocardial biopsy (EMB) is applied to early detect CAR. Although, flexible bioptoms have decreased the incidence of lethal complications, EMB remains an invasive procedure carrying risk of tamponade and permanent heart block. Therefore, a new non-invasive approach is needed. Areas covered: AlloMap molecular expression testing and graft-derived cell-free DNA (GcfDNA) test can be used as blood indices of acute and chronic CAR, respectively...

BACKGROUND: To develop and evaluate a reconstruction framework for high resolution time-resolved CMR of the fetal heart in the presence of motion. METHODS: Data were acquired using a golden angle radial trajectory in seven fetal subjects and reconstructed as real-time images to detect fetal movement. Data acquired during through-plane motion were discarded whereas in-plane motion was corrected. A fetal cardiac gating signal was extracted to sort the corrected data by cardiac phase, allowing reconstruction of cine images...

Across the first four years of life, infants transition from a diet of liquids to solid foods. Flavor preferences affect the acceptance of novel foods. Fetuses experience flavors in the uterine environment, and some preferences appear to be innate. Sweet and salty foods tend to be accepted by most newborns, while bitter tastes are rejected. Breast fed infants appear to have an advantage over formula fed infants, as their exposure to a varying flavor profile is influenced by the mother's diet. Infants are fairly accepting of novel foods, but rejection of new foods increases across the initial years of life...

BACKGROUND: Transplant patients were excluded from the pivotal phase III trials of checkpoint inhibitors in metastatic melanoma. The efficacy and toxicity profiles of checkpoint inhibitors in this cohort of patients are not well described. To the best of our knowledge, this is the first case report of a renal transplant patient with stage IV melanoma treated with a programmed cell death protein 1 checkpoint inhibitor that led to both treatment failure and renal graft rejection. CASE PRESENTATION: We present a case of a 58-year-old white man with a long-standing cadaveric renal transplant who was diagnosed with a B-Raf Proto-Oncogene, Serine/Threonine Kinase wild-type metastatic melanoma...

BACKGROUND: Reduced left ventricular ejection fraction (EF) in the donor heart is often a contraindication for transplant. However, small studies have validated the use of hearts with evidence of myocardial dysfunction to boost the number of organs available for transplant. We hypothesize that donor hearts with reduced EF undergo myocardial recovery after transplant and result in equivalent recipient survival compared with grafts with normal function. METHODS: We examined post-operative outcomes of heart recipients in the database of the United Network for Organ Sharing...

BACKGROUND: Ex vivo lung perfusion (EVLP) was primarily developed for evaluation of impaired donor lungs. The good clinical results raise the question for its possible impact on lungs meeting standard criteria. Before application of EVLP on such lungs enters routine clinical practice, it must be demonstrated whether EVLP would affect or improve outcome when used in standard donor lungs. We performed a prospective randomized trial to investigate the role of EVLP in standard lung transplantation (Tx)...

REVIEW
Samy Talha, Anne Charloux, François Piquard, Bernard Geny
Heart transplantation (HT) should normalize cardiac endocrine function but brain natriuretic peptide (BNP) levels remain elevated after HT, even in the absence of left ventricular haemodynamic disturbance or allograft rejection. Right ventricle (RV) abnormalities are common in HT recipients (HTx), as a result of engraftment process, tricuspid insufficiency and/or repeated inflammation due to iterative endomyocardial biopsies. RV function follow-up is vital for patient management since RV dysfunction is a recognized cause of in-hospital death and is responsible for a worse prognosis...
